- FURNITURE-COUPLING.

SPECIFICATION forming part of'Letters Patent No. 702,623, dated June 17, 19o2.,-

ApplioationfiledMarchlSylQOZ. seam. 98,017. (NomodeL) r To all whom it may concern: I l j Be it knownthat we, JACOB BRUNNER and HIRAM J. ROOT,citizens of the United States,

residing at Shelbyville, in .the .county of Shelby and State of Indiana, have invented new and usefullmp'rovements in Furniture Couplings, of which the following is a specicontiguous parts of furniture and at the same time furnish a brace which will overlie the joint of the connected parts, as will be-here inafter set forth.

The inventionconsists ot' a combined coup-. ling and braceconsisting of a brace-bar, a g I slotted wedge, and. a screw-bolt forconnecting toone part of an 'a'rticle of furniture-the part from which the screw-bolt projects, as.

will be hereinafter described, and pointed out in the claims. 1

In the accompanying drawings,which illustrate the invention, Figure 1 isa perspective to be connected by the coupling one of the parts, as the pillars of a bureau, havingprotheother partsay the top of a bureau'so that the heads of .the screws willpass through view'showing one form of coupling and brace and two parts to be connected thereby. Fig.

2 is a sectional view of the partsconnected.

Fig. 3 is-a perspective View of a modified form of the coupling and brace. Fig.4 is a side elevation of a further modification; and

' Fig. 5 is a rear elevation of'abureau', the'pil- .nected to the braces.

lars or mirror-supportingframe being conbase by the couplings and The brace-bars and couplings, as shown in Figs. 1 andfl, are preferably integral, said oblique on one side and flat on the'othe'r side,

the upper face or flat side of the wedge projecting at right angles with the inner face of the bar. The wedge a has therethrough a keyhole-slot a, the rounded or enlarged part of the slot being through the thinner part of J the wedge.

As a modification of the invention the bar ,or brace a may be separate from the wedge and provided with an aperture a of such a size as to admit of the shank on the wedge being passed through the aperture. The aperture-may be slightlylarger. than the shank of the wedge when a nut-is used upon the shank, as shownin Fig. 4, and when a-nut is not used the aperture 'a i's threaded, as shown in Fig. 3'; The screw-threaded shank projects from the thinner portion ofth'ewedge, and in use when the brace bara is turned the are engaged by the, bolt and wedge.: When the brace bar and wedge are integral, the

wedge will be forced inward todrawlthe parts (wedge will be moved-over the: head of the bolt b, and thus draw together the'pai'ts which 6o together, and suchparts maybe further connected and held by screws, which are passed through the apertures-nearthe ends. of the,

brace-bar and into theconnected'parts.

The tap or screw -bolt bengagesonepart, B,

of the article of furniture, so'that the head:

will 'belocated at asuitable distance from the end of such part, and the other part, O', has a j recess sufficient in size to admit the wedge beneath the head of thebolt,-'saidpart a1so having an opening c','thr'ough which the head 7 f of the tap or screw-bolt m'ay 'bepassed to be engaged by the wedge. 1 j I In assembling parts of furniture which are jecting tap-screws or bolts 1 are placed upon the openings 0 and enter the recesses. The wedges maybe thenpas'sed into the recesses, raised so that the shanks of the bolts willin-I tersect the slots, the inclined faces :of the wedges engaging the heads ofthebolts, such Y heads having been first passed'throughtheenlarged openings at the ends ofthe slot-s.

The wedge is then moved'todraw' the parts undersides of the recesses. v I bemade bya suitable boring-tool which will out when forming the recess the opening c, v the recess intersecting on'eedge to provide an opening through which the wedge ispassed.

The bolt may be adjusted tosu'it the'thick- A ness of the part above therecess and the wedge, and said bolt canbe adjusted to take upany shrinkage that'may occur.

The coupling and brace may be used to con I nect such parts of furniture as have-arighmv j Q angled joint, and the improvement may be pose set forth.

2. A coupling for joints of furniture consisting of a brace-bar, a slotted wedge connected to the brace-bar to project at right angles therewith, a boltcarried by one of the parts which it is desired to connect, an opening for the passage of the bolt and a recess in a part which is to be connected to the firstmentioned part, the wedge entering the re.- cess to frictionally engage the part and the head of the bolt, the brace-bar overlying both of the connected parts, substantially as shown. 7

In a coupling and brace for furniture, a wedge which frictionally engages one part and a headed bolt attached to another part, a bar which overlies the connected parts and to which the wedge is attached, and means for holding the bar against the connected parts, substantially as shown.

4. As an article of manufacture, a furniture fastening or coupling consisting of a bar having apertures adjacent to its ends, a wedge having a keyhole slot therethrough, such wedge being main tained at substantially right angles with the bar, for the purpose set forth.

5. As an improvemcntinfastening devices of the class described, the combination with the case furniture body member having an aperture, of a detachable part which rests upon the body member and over the aperture, said detachable part having an adjustable screw-bolt the headed end of which is passed through the aperture in the body member to position the head beyond the aperture through such part, a wedge which exerts a clamping action upon the head of the bolt and upon the part of the body member adjacent to the aperture, and a brace-bar which overlies the connected parts to hold them in engagement and to hold the wedge against displacement, the brace-bar being positively connected to the parts which are clamped by the bolt and wedge, substantially as shown.

6. As an improvement in fastening devices of the class described, the combination, with the furniture body member having an aperture therethrough, of a detachable vertical back piece the lower edge of which rests upon the body member, a screw-bolt which pro jects from the lower end of the detachable back piece so that its head will be beyond the aperture, a wedge which spans the stem of the bolt and engages the head and the body member adjacent to the aperture through said body member, and a brace-bar which is connected to the wedge and is also connected to the parts which are clamped to each other by the bolt and wedge, substantially as shown.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
